Supervised learning based UEFI pre-boot control
In some examples, a computing device may initiate a chat session with a software agent on a server. During the chat session, the software agent may ask questions and receive answers in response. The server may process logs sent from the computing device and a transcript of the chat session to identify tokens. A supervised learning model on the server may select a script based on the tokens and send the script to the computing device. The computing device may store the script in non-volatile memory and boot into a setup state of a basic input output system (BIOS) of the computing device. The BIOS may retrieve the script, convert BIOS procedure calls in the script into an action tree, and execute the actions in the action tree, causing a virtual mouse and/or virtual keyboard to provide input to the BIOS to modify the BIOS to address an issue.

6. The method of claim 5 , further comprising:
storing, in a namespace of the non-volatile memory, a status indicating whether the script was successfully executed.
7. A computing device comprising:
one or more processors; and
one or more non-transitory computer-readable storage media to store instructions executable by the one or more processors to perform operations comprising:
sending data associated with an issue of the computing device to a server, wherein the data comprises one or more logs stored on the computing device, wherein the one or more logs include at least one of a system log, an error log, or a diagnostic log;
receiving a script from the server;
storing the script in a non-volatile memory of the computing device;
rebooting the computing device into a setup state of a basic input output system (BIOS) of the computing device;
executing the script to modify the BIOS to create a modified BIOS, wherein the modified BIOS addresses the issue of the computing device; and
rebooting the computing device to boot into an operating system.
8. The computing device of claim 7 , wherein the data comprises:
a chat transcript comprising questions sent by a software agent executing on the server and answers corresponding to the questions.
9. The computing device of claim 7 , wherein:
the script comprises one or more BIOS procedure calls.
10. The computing device of claim 7 , wherein storing the script in the non-volatile memory of the computing device comprises:
storing the script in a namespace of the non-volatile memory of the computing device.
11. The computing device of claim 7 , wherein executing script to modify the BIOS to create the modified BIOS comprises:
determining one or more BIOS procedure calls included in the script;
creating an action tree based on the one or more BIOS procedure calls; and
executing each action in the action tree using at least one of a virtual mouse or a virtual keyboard to modify the BIOS.
12. The computing device of claim 11 , further comprising:
storing, in a namespace of the non-volatile memory, a status indicating that the script was either successfully executed or unsuccessful.
13. A server comprising:
one or more processors; and
one or more non-transitory computer-readable storage media to store instructions executable by the one or more processors to perform operations comprising:
receiving, by a software agent, a request from a chat application executing on a computing device to initiate a chat session;
sending one or more questions via the chat session requesting information about an issue associated with the computing device;
receiving, from the computing device via the chat session, one or more responses corresponding to the one or more questions;
processing a transcript of the chat session to create a plurality of problem tokens wherein the processing includes filtering the chat session to remove stop words to create a filtered chat session, and performing natural language processing on the filtered chat session to identify the plurality of problem tokens;
selecting, based on the plurality of problem tokens, a script to address the issue associated with the computing device;
sending the script to the computing device;
instructing the computing device to store the script in a non-volatile memory;
instructing the computing device to reboot into a setup state of a basic input output system (BIOS) of the computing device.
14. The one or more non-transitory computer readable media of claim 13 , wherein the operations further comprise:
instructing the computing device to retrieve one or more logs stored on the computing device;
receiving the one or more logs from the computing device; and
processing the one or more logs while processing the transcript of the chat session to create the plurality of classified problem tokens.
